Water in the 67P comet is not the same as on Earth

67P / Churyumov, The data from the Rosetta satellite device Rosina, which downloaded the Philea spacecraft to a comet called Gerasimenko, has shaken the theory that the world's water source is the comet. Because the data from Rosetta shows that the water vapor in the comet is quite different from the water in our world. Some scientists say, Probably the source of water is the asteroids, ast some say that more data is needed. The Philae probe, carried by the Rosetta satellite, dropped into a comet with a short name of kısa 67P “last month. Rosina, which has two large spectrometers of the satellite, has obtained important data by olan sniffing ’gas streams on the surface of 67P. Scientists studying the data concluded that the water contained in the comet, an ice mass of mountain, is different from the water on our planet, three times the amount of water in the world.
The water in the world is different from the water in the world. One of the hydrogen atoms in the water molecules, consisting of two hydrogen and one oxygen atom, is rarely replaced by a deuterium atom. This ratio in the earth on every 10 thousand water molecules in the form of 3 deuterium atoms. Water with deuterium atoms also has the same physical properties as water containing two hydrogen and one oxygen atom. However, the deuterium water is heavier. One of the scientists who studied Rosina's data is Professor Kathrin Altwegg of the University of Bern in Switzerland. . This ratio between heavy and light water is very characteristic. It doesn't change easily, and it stays the same for a long time, suy he says. Recent findings are evaluated together with the findings of other studies analyzing water in other types of comets. In previous studies, it was revealed that the water in the comets that belonged to an area called Oort Bulut and located in a farther corner of the Solar System was different from the world. Only from the Kuiper belt extending up to Neptune, only two comets could be examined. One of them is the 67P and the other is Hartley, whose water resembles the world. But Altwegg says the comets in the Kuiper belt cannot be the source of water in the world. According to him, comets on this belt have both heavy and light water. Even their composition is heavier than water in the world.

Yet early olma According to Kathrin Altwegg, the asteroids, which are closer to the Sun than the comets, are dense and rocky bodies, are more likely to be the world's water source. Altwegg says that they acquire information by working on methotoids that are part of the asteroids, and think that these bodies are much closer to Earth, so the probability of striking the Earth is more than the distant comets beyond Neptune. However, according to some other scientists, it is too early to throw away the ’comet theory Ancak. Alan Fitzsimmons of the Center for Astrophysics Research at Queens karşıs University, Belfast, opposes the fact that Altwegg has averaged the water in the comets of the Kuiper belt. According to Fitzsimmons, we do not know how the stars with high-deuterium water and the low ones hit the Earth. So we need more data. Professor Monica Grady says that Rosita was measuring with the gases rising from the surface, and that the amount of hydrogen atoms changed as the water passed from the liquid state to the gaseous state. Tüm All data from Philae should be expected, Gr says Grady.
